Word Embeddings
Word Embeddings are a way to help computers understand and work with human language. Think of them as a system that converts words into numbers that computers can process, where similar words end up with similar numbers. This helps AI systems understand that words like "car" and "automobile" are related, or that "king" and "queen" have a similar relationship as "man" and "woman". This technology is a fundamental part of many modern AI applications, especially in tasks involving understanding text, translation, or chatbots. You might also see this referred to as "Word Vectors," "Neural Word Embeddings," or "Word Representations" in job descriptions.

Example Interview Questions
Senior Level Questions
Q: How would you choose between different types of word embeddings for a specific project?
Expected Answer: A senior candidate should explain how project requirements like language complexity, available data, and computing resources influence the choice. They should mention trade-offs between pre-trained solutions and custom training approaches, considering factors like accuracy and implementation time.
Q: How would you handle domain-specific vocabulary in word embeddings?
Expected Answer: Should discuss approaches for adapting general word embeddings to specific industries, fine-tuning existing models with domain-specific data, and methods for handling technical terms or jargon not found in standard embeddings.
Mid Level Questions
Q: What are the main differences between Word2Vec and GloVe?
Expected Answer: Should be able to explain in simple terms that these are two popular ways to create word embeddings, with Word2Vec learning from context and GloVe using statistics about how often words appear together.
Q: How do you evaluate the quality of word embeddings?
Expected Answer: Should describe basic testing methods like checking if similar words cluster together, using standard benchmark tests, and practical ways to verify if the embeddings work well for the specific task.
Junior Level Questions
Q: What is the basic concept of word embeddings?
Expected Answer: Should be able to explain that word embeddings convert words into numbers (vectors) so computers can process them, and that similar words have similar number patterns.
Q: How do you use pre-trained word embeddings in a project?
Expected Answer: Should demonstrate knowledge of how to load and use existing word embeddings like those from Google or Stanford, and basic integration into simple applications.
